CONVEYER-BOLLER.

Specification of Letters Patent.

Patented May 31, 1910.

Application filed December 27, 1909. Serial No. 535,095.

To all whom it may concern:

Be it known that I, SIGMUND L. GOLDMAN, a citizen of the United States, residing at 3900 Union avenue, Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Conveyer- Rollers, of which the following is a specification.

My invention relates to an improvement in the cla s of rollers used in. gravity con veyers; and it is illustrated in the accoming drawing, in which Figure l is a broken and partly sectional view in elevation of my improved roller in position in the side-members of a conveyerframe, and Fig. 2 is a broken perspective view showing parts of the roller in unassembled relation.

The essential parts of my improved roller are a cylindrical tube 3, preferably of steel,

- heads 4 having annular shoulders 5 at which they are pressed intothe ends of the tube, a shaft 6 extending lengthwise and centrally through the tube and heads and having its ends threaded, and similar journaling-nuts 7 of peculiar construction adapt-ing them to be screwed on the ends of the shaft and form the roller-journals to seat in' the op osite side-members 13, 13 of a conveyerrame, centering means for the tube on the shaft and substantially frictionless spacers between .the heads and frame-members. The nut comprises an internally-threaded sleeve 8 terminating in a head 9, shown of hexagonal shape, with a nipple 11 projecting centrally from its face; the outer side of the nut being beveled, as shown, to form a frictional bearing surface 12 of relatively small or reduced area.

with extreme ri 'dity, the com arativel f extensive area 0 the inner nut-' aces ten without riveting or ,further fastening, to hold the heads in place against angular slanting, or other displacement in the tubeends, and the reduced area of the nut-faces 12 presents 'so little surface to the inner sides of the frame-members 13 as to render ne ligible the friction against turning the ro ler on its journals 8 in the frame-member bearlngs. manently fasten them together the ends of the. shafts may be upset or riveted, as shown.

The more important advantages of the construction thus described lie in its com-t parative simplicity, cheapness of manufac ture, strength, rigidity and durability, which are the qualities most sought for improvementin the art.

WVhat I claim as new and desire to secure by" Letters Patent is':

1. A conveyer-roller comprising, in cofnbination, a tube, heads on the tube-ends, hav- When the parts are assembled to pering central openings, a shaft extending nuts bearing at their'inner faces against the opposite heads about the openings therein.

3. A conveyor roller comprising, incombination, a tube, heads on the tube-ends pro.- vided with central openings, a shaft extend ing. through the head-openings, and nuts, each consisting of a journal-forming sleeve screwing on a shaft-end, and terminating in a spacing-head havin an inner face of relatively great area. wit a nipple rojecting therefrom into a head-opening, and an outer surface ofirelatively small area.
